Whirlpool compactor Switch Complications

Having complications with replacing the switch to this whirlpool compactor motor, the switch I ordered is part number 777971, the problem is the model number is a different number. I need a better explanation of the wiring diagram and can not get the switch/motor to run, I still have the old switch. The information that comes with the switch with wiring it does not help, if anyone knows how to fix this problem or knows where I can get help on fixing this problem it would be much appreciated.
